Example 1 with SqlRegularColumn

use of org.apache.flink.sql.parser.ddl.SqlTableColumn.SqlRegularColumn in project flink by apache.

the class SqlCreateHiveTable method unparseColumns.

private void unparseColumns(HiveTableCreationContext context, SqlNodeList columns, SqlWriter writer, int leftPrec, int rightPrec) {
    List<SqlHiveConstraintTrait> notNullTraits = context.notNullTraits;
    int traitIndex = 0;
    for (SqlNode node : columns) {
        printIndent(writer);
        SqlRegularColumn column = (SqlRegularColumn) node;
        column.getName().unparse(writer, leftPrec, rightPrec);
        writer.print(" ");
        column.getType().unparse(writer, leftPrec, rightPrec);
        if (column.getType().getNullable() != null && !column.getType().getNullable()) {
            writer.keyword("NOT NULL");
            notNullTraits.get(traitIndex++).unparse(writer, leftPrec, rightPrec);
        }
        column.getComment().ifPresent(c -> {
            writer.keyword("COMMENT");
            c.unparse(writer, leftPrec, rightPrec);
        });
    }
}

Example 2 with SqlRegularColumn

use of org.apache.flink.sql.parser.ddl.SqlTableColumn.SqlRegularColumn in project flink by apache.

the class OperationConverterUtils method toTableColumn.

private static TableColumn toTableColumn(SqlTableColumn tableColumn, SqlValidator sqlValidator) {
    if (!(tableColumn instanceof SqlRegularColumn)) {
        throw new TableException("Only regular columns are supported for this operation yet.");
    }
    SqlRegularColumn regularColumn = (SqlRegularColumn) tableColumn;
    String name = regularColumn.getName().getSimple();
    SqlDataTypeSpec typeSpec = regularColumn.getType();
    boolean nullable = typeSpec.getNullable() == null ? true : typeSpec.getNullable();
    LogicalType logicalType = FlinkTypeFactory.toLogicalType(typeSpec.deriveType(sqlValidator, nullable));
    DataType dataType = TypeConversions.fromLogicalToDataType(logicalType);
    return TableColumn.physical(name, dataType);
}

Example 3 with SqlRegularColumn

use of org.apache.flink.sql.parser.ddl.SqlTableColumn.SqlRegularColumn in project flink by apache.

    List<SqlTableConstraint> ret = new ArrayList<>();
    this.columnList.forEach(column -> {
        SqlTableColumn tableColumn = (SqlTableColumn) column;

            regularColumn.getConstraint().map(ret::add);
        }
    });
    ret.addAll(this.tableConstraints);
    return ret;
